Endovascular Management of Venous Thromboembolic Disease in the Oncologic Patient Population

Venous thromboembolic disease causes significant mortality and morbidity in the oncologic patient population. Recently, minimally invasive endovascular technologies have been developed as an adjunct to antithrombotic therapy for the management of DVT and PE. The current and potential roles for endovascular treatment of cancer-associated venous thromboembolism (VTE) will be reviewed in this article.

The recent NCCN guidelines recommend endovascular therapy in patients eligible for therapeutic anticoagulation who present with life-, organ-, or limb-threatening thrombosis. However, symptomatic non-life-threatening VTE can negatively affect QOL and physical function, both of which have prognostic implications in the cancer population. Endovascular therapies have been shown to improve physical function and QOL in prospective trials performed in a non-oncologic patient population as well as small retrospective studies in the cancer population. In addition to treating life- and limb-threatening thrombosis, endovascular therapy for VTE can improve QOL and physical function in comparison to anticoagulation alone. Prospective trials are warranted to assess the benefit of endovascular therapy for quality of life-years, performance status, and overall survival in the oncologic patient population.
